Influence of the Weaving of Weld Line on the Fatigue Strength

概要

Fatigue strength of butt joints welded with weaving has been investigated for SM58 steel by the fatigue test under pulsating tension. The specimens are classified into 6 groups by the weaving angle ranging from 0 to 45 degrees, and the amount of transverse shift of welding torch is ±2mm. Zero degree of weaving angle means a straight weld line. When the weaving angle is changed, the geometrical shape at the toe of weld is consequently transformed. The fatigue strength is influenced by both the weaving angle of bead and the geometrical shape at the toe of weld. It was found that the fatigue strength increases as the weaving angle increases.
